Hallo Jürgen, the palps are not dilated apically and distinctly shorter than proboscis which seems to be longer than the head's height. I think it is
Stomoxys calcitrans.

Thanks, Eric! I excluded
Stomoxys calcitrans, because I had it in mind with a much thinner proboscis, not thickened at the base like in this fly. But I mostly see it when it rests with the proboscis straight forward like on the picture below.
